“…Moreover, field guides often neglect the known overlap between small felid footprint size and shape, as well as the possible bias introduced by the presence of domestic cats (Felis catus), which often become feral [9]. Several authors have adopted more conservative methods, providing identifications to the genus level [11,[15][16][37][38][39][40][41][42], or only associating footprints with species when (1) individuals were observed by the team [41,43], (2) settlers confirmed the species presence in face-to-face interviews [42], or (3) in the presence of complementary methods (e.g., scats collected near footprints are identified by molecular techniques or microscopic analyzes of fur found in feces [44]).…”

Carnivores, particularly felids, face threats in many regions of the world. They are a crucial component of biodiversity with a functional role in the top of the food chain. Therefore, they have been the target of surveys and monitoring and ecological studies, most of which are based on footprint identifications, an efficient and low-cost method compared to other approaches. In these cases, species identifications may suffer from a high degree of bias due to the overlap in the size and shape of footprints among species. We experimented with small to medium captive wild felids of five species: ocelot, Leopardus pardalis, margay L. wiedii, oncilla, L. guttulus, domestic cat, Felis catus, and jaguarondi, Puma yagouaroundi). We tested for differences in footprint measurements, including main pad and toe pad sizes. We used humid sand as substrate and took measurements from several front and hind footprints of seven animals per species (except jaguarondi, for which only four animals were available). Our results showed that ocelot is the only species for which it is possible to obtain 100%-accurate footprint identifications, mainly because of its footprint area ( i.e., length × width). The remaining species presented a wide variation in measurements, making them almost impossible to distinguish based solely on footprint dimensions. Our results suggest that researchers should restrict identification to the genus level or adopt a multidisciplinary sampling strategy by combining footprint detection with camera-trapping, visual observation, scat collection, molecular ecology techniques, and/or face-to-face interviews with local residents.

RESUMENA pesar de los cambios antrópicos en los Andes colombianos, todavía se encuentran relictos de ecosistemas nativos con valor para la conservación, siendo los únicos remanentes de hábitat para vida silvestre en áreas cercanas a grandes ciudades. Presentamos resultados de una investigación realizada en la Reserva privada Passiflora (cerca de Bogotá), que buscó examinar la diversidad de la comunidad de mamíferos no voladores. Combinando diferentes métodos encontramos 17 especies, pertenecientes a siete órdenes, que sugieren que ésta es una comunidad compleja a pesar de la intervención antrópica en la zona. Destacamos la presencia de especies raras o endémicas como Olallamys albicauda, Cuniculus taczanowskii y Leopardus tigrinus. Nuestro estudio indica que pese a la transformación de los Andes colombianos, es posible encontrar elementos representativos de su mastofauna incluso en pequeñas reservas privadas, añadiendo valor a estas iniciativas particulares que complementan las iniciativas nacionales de conservación de la biodiversidad.Palabras clave: ecosistema andino, fragmentación, inventarios de fauna. ABSTRACTDespite the anthropic changes in the Colombian Andes, there are still several relicts of native ecosystems with conservation value, which are the only habitat remnants for wildlife in areas near large cities. We present results of a research conducted at the Passiflora private Reserve (near Bogota) which aimed to evaluate the diversity of the community of non-flying mammals. Combining diverse methods, we found 17 mammal species, belonging to seven orders, suggesting a complex mammal community despite the human intervention in the area. Besides, we highlight the presence of rare or endemic species such as Olallamys albicauda, Cuniculus taczanowskii and Leopardus tigrinus. We conclude that despite the transformation of the Andes, it is still possible to find representative elements of Andean mammal fauna, even in private small reserves, adding value to these particular initiatives, which complement the government conservation efforts.

“…According to a mammal census conducted in the RPSP in 2006, there is no record of any sloths occurring in this area (Oliveira et al, 2013). Although this census was based mostly on footprints found along roads and transects, the lack of records for Bradypus spp.…”

“…The capões of the Espinhaço Range have a high floristic similarity with the semi-deciduous forests associated with the Atlantic Forest of southeastern Brazil (Coelho, 2014). Such vegetal formations and the occurrence of the primate Callithrix geoffroyi (Humboldt, 1812) in the RPSP (Mesquita & Passamani, 2009;Oliveira et al, 2013), a typical species of the Atlantic Forest, indicate that the region is an ecotone zone between this biome and the Cerrado.…”

Little information is available on the occurrence of sloths in the Cerrado biome in Brazil. Here, we present the first record of Bradypus variegatus in the Cerrado sensu stricto, for the state of Minas Gerais, and possibly for the entire biome. We recorded an adult female at Rio Preto State Park, resting on a mangaba tree (Hancornia speciosa) at an altitude of 1,093 m. The presence of a gallery forest 200 m away suggests that the animal could have come from this and was in the process of dispersal. The sloth populations that may exist in this biome should represent unique ecological, genetic, and morphological adaptations that are worthy of study.
